This invention relatesv to improvements in detachable horseshoe calks.

It is one of the objects of the present invention to provide resilient horseshoe calks to prevent slipping, especially adapted for summer use, and which calks are readily detachable without removing the shoe from an animals hoof.

VA further object of the invention is to provide a resilient horseshoe calk of the detachable type whichwill'not work loose `from 'the shoe when in use.

A further object of the inventionv 'isrto provide va detachable padded horseshoe calk which is of veryV simple construction, 1s 1nexpensive to manufacture, is easily `mounted on a horseshoe andremoved therefrom for replacement, is strong and durable, and is well adapted for the purposes described.

With the above'and other-'objects in view the invention consists. ofthe improved detachable paddedthorseshoe calk and its parts and combinations-as set forth in the claims, and all equivalents thereof.

Inv the accompanying drawing in which the same reference characters indicate the same parts in all of the views: e

Fig. l is an inverted plan view of a horseshoe provided with the improved detachable padded calks;

Fig. 2 is a side view thereof; p

Fig. 3 is an inverted plan view ofa horseshoe provided with detachable padded calks of a slightly modified form; i 1

Fig. 4 is a side View thereof;

Fig. 5 is an enlarged detail sectional view taken on line 5 5 of Fig. 4; and

Fig. 6 is an enlarged detail sectional View illustrating another modified tachable padded calk.

Referring now more particlarly to the drawings, with special reference tothe form of the invention illustrated by Figs.` 1 and form of a de- 2,v it will appear that the numeral 8 indicates a horseshoe having in its front portion a pair` of spaced upwardly, inwardly tapered openings 9, and two pairs of similarly shaped and spaced openings 10` in its rear or heel portion. v

The improved padded calks are adapted kfor detachable insertion in the pairs of openings 10 and also in the pair of openings 9, if desired, but as illustrated, the padded calks are shown only in the openings 10. Each calk member 11 comprises a pair of spaced metallic members having tapered Shanks 12, tapered outer stems 13, and'medial enlarged flaredl or anchoring portions 14. The stem and flared portions of a pair of metallic members are embedded lin a pad 15 of rubber or other similar resilient material, as Shownin Figs. 1 and 2, and said pad is shaped as shown in said ligures and underlies a substantial portion of the horseshoe 8.

It will thereforebe seenthatjin the prin- 17" -may'be replaced `by one yof the double-- padded i calks shown `mounted portion oftheho'rseshoe. i i

The improved form of padded calks will not work loose from the horseshoe when in in the' rear use. `Asfshown in Fig.y 2 the tapered stem i portions `13 of eachcalk terminate quite close tothe lower outer surface ofthe pad and hence when the horseshoe is secured onto a horse?s"'hoof` in iwalkin'g therepwill be a direct pressure applied `to' the outer ends-of the stem, so thatat vall times, during use, the

lnjessure on said stem portions will force the shank portions of the metallic members intothe tapered openings 10.` When the improved padded calks become worn and itis desired vto replace the same, they may be readily removed from the horseshoe without the necessity of removing the shoe from the animals hoof; -This is accomplished by the application ofa tool applied between the upper ysurface of the calk pad and the under' v wedgingly engaged in an aperture 1() and an outer stem 13 and an intermediate flared portion 14, both of which are embedded or molded in aresilient padl, of circular form in cross-section. Said single-padded calks are applied as shown, and they also may beemployed in the forward openings 9 of the horseshoe in lieu of the metallic calks 17.

A further modification of the invention is illustrated in Fig. 6 wherein the numeral 16 indicates a portion of the horseshoe provided with an upwardly tapered and threaded opening 18. The calk includes a metallic member having a tapered and externally threaded shank 12 and a` depending outer stem portion 13. Between the portions 12 and 13 is an annular enlarged portion 14 and an enlarge angular tool-engaging poition 19. Said vmetallic portions 13 14', and a portion of the tool-engaging portion 19 are embedded in a resilient pad member 15', of circular form in cross-section. In use the threaded Ashank portion 12 of the calk is threaded into the opening 18 of the horseshoe and the angular portion 19 permits the application vof a tool for this purpose. To remove the calk for replacement a tool is applied'to the portion 19 and the shank portion 12 is unthreaded from the opening.

It will therefore be seen that the present invention contemplates the provision of a padded, resilient horseshoe calk which is readily removable from a horseshoe without the necessity of removing the horseshoe from the animals hoof. Also, in use the calk is so arranged thatthe tendency is for it to become opening and also having an outer stem portion and an intermediate anchoring portion, and a resilient pad member secured onto and covering said stern and anchoring portions, said stem terminating at its outer end relatively close to the lower surface of said pad so as to be the direct recipient of pressure applied to the lower surface of the pad.

3. A padded horseshoe calk, comprisng an elongated resilient pad adapted to underlie a substantial area of the undersurface of a horseshoe, and a pair of spaced metallic members, each metallic member having an outer stem portion, an intermediate anchoring portion, and an inner tapered shank portion, said stem and anchoring portions of the pair of metallic members being spacedly embedded in said pad with their outer ends terminating relativelyv close to the lower surface of said pad, the tapered Shanks of said metallic members being wedgingly insertable in a pair of tapered horseshoe openings.

4. The combination with a horseshoe having an opening therein, of a removable padded calk, comprising a metallic member having a shank removably inserted in said opening and also having a stem and an intermediate lared anchoring portion, and a resilient pad securely mounted on and enclosing said flared anchoring portion and the stem, a portion of said pad being interposed between the horseshoe and said flared anchoring portion whereby said horseshoe is cushioned. l

Inl testimony whereof, we aix our signatures.

firmly engaged by the horseshoe rather than to work loose. The improved detachable padded horseshoe calk 'is also simplel and novel, and is well adapted for the purposes set forth. r

What is claimed as the invention is Y 1. A padded horseshoe calli, comprising a metallic member having an inner shank portion removably engageable with a horseshoe and an outer stem portion, and a resilient pad member secured onto and completely enclosing said outer stem portion, the outer end portion of said stem terminating inwardly of the bottom of the pad and being'covered thereby. 2. A padded horseshoe calk, comprising a metallic member having an inne-r shank portion removably lodgeable within a horseshoe
